Energy Usage of My Computers (Kill-A-Watt)

Getting a fine gift, A Kill-A-Watt device, from my Sister and Brother in-law last year meant I could measure the energy usage of my computer systems. Not necessarily a HOWTO article, but informative for those of us that obsess over numbers and metrics.

The Server Closet contains:
(1) Server (512MB/AMD Athlon(tm) XP 1600+)
(2) D-Link DI-724GU Router
(3) Comcast Cable modem (Motorola SB5120)
(4) Vonage Phone Adapter (Motorola VT1005V)
(5) Oregon Scientific WMR-968 Weather Station
- Note No Monitor

Power Usage:
1.34 Amp
125 Watts
2.95 KWH per day

My Primary System consists of:
(1) User System (1GB/Pentium 4 - 3.00GHz)
(2) Monitor 1 - Dell 2001FP 20" LCD
(3) Monitor 2 - Sony GDM-500PS CRT
(4) Sound - Yamaha Receiver RXV420, KLH Speakers and Subwoofer Model HTA-4906.

Power Usage:
3.06 A
300 - 400 Watts (depending on whether it is rendering in game or relaxing writing a document)
4.30 KWH per day

Our computer room is on a 15 Amp fuse and it now makes sense when my wife's computer system is on and she turns on an electric space heater my resulting trip to the fuse panel. Given the above, I now expect that fuse is probably even being lenient on us, given her system probably uses 3.0 Amps (identical system).

Keywords: computer, power usage, watts, how much power does my computer consume

I hesitate to trouble you with such a trivial question. However, since you seem to be the helpful sort... How does one arrange for multiple dynamic IPs with Comcast? Their online docs are rather uninformative.

Sounds like a challenge and I am willing to help out as much as possible. I'll try and figure this out with you. I'll contact you through your blog.
